This is actually the second iteration of the PCB. At first I used one of the PCB's that I had from the Scorpion 3.0 project. I trimmed the extremities of the PCB and used only the middle part with the MCU, OpAmp shunts and regulator. I wrote the first version of software using this refurbished PCB and then I redesigned the entire thing.
